Is the C6R the same as the C150HD?

Anyone? I'm pretty sure that these are both 150mm f/8 C-F achromats from Celestron, but are the parts interchangeable? Let me know, please.

The C150HD that I know of was a 6 inch Hybrid/short tube Newtonian. Is there also a refractor that was sold as the C150HD? I googled around a bit and I only found the reflector...

The CR-150 HD preceded the C6-R and did not originally have a collimatable lens cell, though I've been told later models of the CR-150 did start having them until Celestron designated them C6-R. Parts (focuser ,tube rings, optics) should be interchangeable except for the smaller dew-shield used by the original non-collimatable CR-150 HD refractor and the different lens cell.
